Device Authorization Endpoint

The client library for the OAuth 2.0 device flow device authorization is provided as an extension method for HttpClient.

The following code sends a device authorization request:

var client = new HttpClient();

var response = await client.RequestDeviceAuthorizationAsync(new DeviceAuthorizationRequest
{
    Address = "https://demo.identityserver.io/connect/device_authorize",
    ClientId = "device"
});

The response is of type DeviceAuthorizationResponse and has properties for the standard response parameters. You also have access to the the raw response as well as to a parsed JSON document (via the Raw and Json properties).

Before using the response, you should always check the IsError property to make sure the request was successful:

if (response.IsError) throw new Exception(response.Error);

var userCode = response.UserCode;
var deviceCode = response.DeviceCode;
var verificationUrl = response.VerificationUri;
var verificationUrlComplete = response.VerificationUriComplete;
